Title: Method and apparatus for demodulating  signals in a logging while drilling  system
Inventor: WAGGENER WILLIAM N
IPC: E21B47/12
Filed: 1979-02-26
Granted: 1982-06-29
Abstract: The disclosure is applicable for use in a logging-while-drilling apparatus for obtaining subsurface measure-ments during drilling in a  fluid-filled  borehole.  Acoustic carrier waves are generated downhole in the borehole fluid and are PSK modulated in accordance with digital data representative of downhole measurements. The PSK modulation is obtained by momentarily unidirectionally either decreasing or increasing frequency of the acoustic carrier signal until either a desired phase lag (for a decrease in frequency) or phase lead (for an increase in frequency) is imparted to the acoustic carrier signal.  An uphole receiving subsystem includes transducers for converting the modulated acoustic carrier waves to electronic signals and circuitry for de-modulating the electronic signals to recover the measurement information taken downhole.  In accordance with an important feature of the invention, a filter is provided for selectively filtering the electronic signals before the demodulation thereof The filter is provided with a bandpass characteristic having a center frequency which  is displaced from the nominal frequency in the direction of the unidirectional decrease or increase of frequency applied when originally modulating the acoustic carrier waves.  The center frequency is preferably offset from the nominal carrier frequency by an amount which is a function of the bit rate of the digital information,  preferably an amount equal to one-half the bit rate of the digital information.  In the preferred embodiment of the invention, the bandpass characteristic of the filter means is skewed in the same direction as the offset.

Abstract: IMPROVED ASPHALT MIXTURE                           ABSTRACT   A process for preparing an improved asphalt mixture by adding coal materials thereto. Low carbon content coal materials are separated into first and second portions, the first portion being soft-burned at approximately 600°F and the second portion being exposed to a number of wetting and drying cycles, followed by a thorough leaching. The first and second portions are crushed and screened to produce a fine particulate coal material having a maximum diameter passing through a 200 mesh screen, and a larger size coal material having a maximum diameter of 3/4 of an inch. In a first embodiment, an asphalt paving material is produced by adding the fine particulate coal materials to an asphalt-aggregate mixture in a proportion of approximately 75% of the first portion and approximately 25% of the second portion of the fine particulate coal materials, such that the coal materials equal approximately 6 to 8% by weight of the total mixture. The resulting asphalt mixture is heated at approx-imately 300°F., and may be stored at this temperature in order to increase the mechanical bonds between the asphalt and aggregate. In a second embodiment the larger size coal materials and/or the fine particulate coal materials are used as a filter medium to remove pollutants from a liquid effluent stream, and are then added to an asphalt mixture with the fine particulate coal materials in the same prop-ortions as in the first embodiment. The asphalt-coal mater-ial mixture is then heated at approximately 300°F, and may be stored for a period of time to increase the mechanical bonds between the asphalt and coal materials. The resulting mixture may be compressed into any desirable shape, the poll-utants being effectively sealed within the coal materials, providing safe and efficient long term storage or disposal.

Abstract: ABSTRACT      The hot raw synthesis gas stream leaving the reaction zone of a free flow partial oxidation gas generator at a temperature in the range of about 1800° to 3000°F. is passed through a first gas diversion and residue separation zone where the velocity of the gas stream is reduced and its direction is diverted into a side transfer line.  Solid material and molten slag separate by gravity from the gas stream.  the hot gas stream is then introduced into a second gas diversion and residue separation zone where  additional residue is separated. About 0.5 to 20 vol. % of the hot gas stream may be passed through bottom outlets in said first and second gas diversion zones in order to prevent bridging. The hot gas stream from the second gas diversion zone is passed upwardly through a radiant cooler where additional solid matter is removed by gravity and the gas temperature is reduced to a temperature in the range of about 900° to 1800°F.  In one embodiment, the second diversion and residue separation zone is a thermally insulated cyclone. By the subject process, 70 to 95 wt. % of the combustion residue is removed from the raw stream of synthesis gas, and the temperature of the gas stream is reduced below the maximum safe operating temperature for downstream devices used to recover energy from the hot gas stream such as  a conventional convection type gas cooler.
